Specification of Letters Patent. PaiggntgdAu 10 1915.

Application filed April 29, 1914, Serial No. 885,147, Renewed. duly 12, 1915. Serial No. 39,498 i 'a citizen of the United States, residing at Richmond, 'in the county of Henrioo and State of Virginia, have invented a new and useful Ventilator for Car-Windows, of which thefollowing is a specification.

My invention relates to a Ventilating and defiectingscreen, especially adapted for use in sleeping car windows, but which is also adapted for general use.

My object is to provide improved novel means for ventilation, novel means for defleeting cinders, rain, etc, and novel and improved means for inserting a device of this kind beneath a raised window and engaging it with the window sash and window frame.

It is also my object to provide novelmeans for adjusting one of the panel members in my screen so that it may operate more easily.

It is a further object of my invention to providenovel means for securing an adjustable panelin my screen to its raised position for modifying the ventilating effect of the device when desired. a p L V It is my further object to combine the various features of my ventilating and deflecting screen to form the novel device disclosed herein, whereby to provide ventilation and to" make the employment of an additional deflector for car windows unnecessary with this device.

i I attain these objects by the mechanism illustrated in the accompanying drawings, in which' Figure 1 is an elevati'onal view of my screen, partly in section, in operative position beneath a window, one of the inner panels being shown in raised position; Fig. 2 is a longitudinal section on line 2-2 of Fig.

I 1; Fig. 3 is a vertical section on line 33. of

Fig; 1; Fig. 4 is a vertical section of a modified form of the invention; Fig. 5 is a longitudinal section of one of the casing or screen frames, showing the preferred form of means for securing the lower panel in raised position; Fig. 6 is a detail view of upper corner of the screen frame; Fig. 7 is a detail'view of part of the screen frame; andFig; Sis a detail view of member Q.

Likel'etters indicate like parts in the various views. a

,My ventilating and deflecting screen has twolike sections, casings or screen frames, indi'cate'din Figs. 51 and 2 by A and B.

These frames are pivotally connected or hinged as shown in Fig. 2 to permit of the convenient insertion and removal. of the device 1n. a portion of a window frame. The

pivotal,connectingmeans which I prefer to employ are hinges C, disposed as shown. in

Fig. 2, mounted on adjacent frame inner members D, with the pivotal portion of the hinge disposed adjacent the outer portion of those members, whereby to permit the insertion of the screen frames in awindow casing from the inside of a buildingor car without having the screen frame project at anytime beyond the plane of the window casing. This is a'fcature of vital importance in the application of my device to car windows, as it can be inserted and removed from within, and without projecting it beyond the car casing where it would be a source of danger.

Each outer frame side member E is provided with a projecting portion F adapted to engage in the window casing to form a rabbeted joint (see Figs. 2 and 6), with the objects of securing the screen more firmly in place and also .to prevent cinders or water from drifting in.

Each screen frame top member G is provided with a rabbet .or'recessed portion H,

asshown in Figs. .3, 4 and 6, with which the bottom sash of the window may engage, thus forming therewith a rabbeted joint when the screen is adjusted in position beneath a window. Members G are provided with an outwardly and downwardly-inclined or defleeting portion I, as shown.

Each screen frame bottom member J is provided with a deflecting outwardly and downwardly-inclined surface -K, as indicated in Figs. 3 and L. In the outer portion there is provided a reticulated member or screenL, as shownyin Figs. 2 and 8. It is within the contemplation of my invention to providea likereticulated or screen member, adjacent the inner portion of each frame, as indicated in the modified form of my invention illustrated in Fig. 4, 'orat any other suitable portion of the frame or casing.

of each screen frame I provide novel means for ventilation, comprlslng a top panel 'M mounted in the upper portion of each frame, and a bottom panel N mounted in the lower portion of each frame and spaced'substantially apart from panel M, which, in the "preferred form of my invention, is substantially as shown in Fig. 3, or in the modified form is'substantially as shown in Fig. 4. The ventilating effect is, however somewhat modifiedby the disposition of panels M and N asdisposed in Fig. 4, as distinguished from the disposition of panels M and N in the preferred form of my in'ventionillustrated in Fig. 3. As shown in Fig. 3 I employ panels M and N having their unincased or outer edges in approximately the same horizontal plane, or

more specifically, in a horizontal plane to or beyond which each of the edges m and n extend. In the modified form shown in Fig. i I provide panels M and N having edges-m and n extendingsubstanti'ally past a horizontal plane that would pass through both panels, diagonally disposed one from the other. a I r In the preferred forms of my, invention, illustrated inFigs. 1, 2, 3 and 5, bottom panel N is slidably mounted in grooves O in side member-s1? and D of each screen frame, as shown. Means for raising and lowering panel- N are provided, preferably consisting of a button or handle P, Means for. retaining the lower panel N in raised position whendesired are provided. Preferably I employ novel springs M mounted in grooves O to frictionally engage and sup port panel N when raised, as will be understood by referring to Fig. 5; or I provide a suitable arm Q secured to button of handle P, and which may be rotated from horizontal to vertical position to retain panel N in raised position, as shown in Fig. 1 at the right of that figure. Arm Q, is preferably of the form shown in detail in Fig. 8 and normally disposed horizontally against panel N, but may be disposed in vertical position at will, to support the panel when so desired.

Means for preventing panel N from sticking and insuring its being freely movable under all conditions may be provided, consisting of rollers R,wmounted as shown in Figs. 1, 3 and 7, engaging the sides of the 7 panel.

As already indicated, the screen is operated by opening it outward from a folded position, to engage with a window casing, it being inserted beneath a partially raised window from within a car or building. Projecting' tongues F of the outer frame side members E engage with the corresponding grooved portions of the window casings, and the bottom sash of the window engages with the rabbeted or recessed portion H of the screen frame top members G. Reticulated members or screens L (and L when used) eXclude'cinders, etc.; and rain, cinders, etc., aredeflected by panels M and N also. Defiecting or inclined surfaces K defiect water from the screen frame, and deflecting portion I of top member Gr performs a similar function Ventilation is afforded as the result of substantially spacing apart panels M and N, air from outside being afforded an entrance between the panels, as will be apparent from the drawings. By having the outer or unincased' edges of panels M and Nterminate in a substantially like horizontal plane a novel construction is presented, which permits free ventilation, with which iscombined the function of deflecting cinders, rain, etc, by the deflecting surfaces which the panels provide and which is a more effective means than screening arrangements heretofore in use. The form of my invention illustrated in Fig. 4:, presents a novel disposition of panels A and N, to afford additional or more extensive deflecting surface while at the same time affording ventilation.

Novel means for adjusting the lower panel to a raised position, at the desire of the user is provided and operated as hereinbefore set forth, the panel being slidable'to the top of the frame. Novel rollers R engaging the side edgesof the panel prevent its becoming wedged against thegrooves in which it is mounted, and insures easy operation at all times.

It is within the contemplation of my invention to construct my ventilating and defleeting screen of metal, wood or other suitable materials. Minor changes not involving the novel operation of my screen are also within the contemplation of my invention, and particularly I do not limit myself to a particular size or proportion of parts.

What I claim is:

1. A ventilator adapted to be inserted be- 'neath a window in the sash grooves, comprising a plurality of frame sections each provided with a ventilating orifice, means pivotally connecting the adjacentends of the sections at the edges exterior to the window when in place, whereby the ventilator may be inserted in the sash grooves without extending the central portion out of the car.

2. A ventilator having the top portion of the frame recessed from the inner edge of said frame member to a line intermediate between its inner and outer edges to afford a recess spaced apart from the outer portion of the ventilator for the reception of the bottom portion of a window sash and having the top portion of the frame beyond the recessed portion thereof disposed on a plane upper panel lying in a plane exterior to the mner panel; and means for retaining the inner panel in raised or open position in the ventilator 7 frame.

4:. A ventilator adapted to be inserted beneath a window in the sash grooves, comprising a plurality of, pivotally connected frame sections each having laterally projecting tongues formed on the side frame portions adapted to seat in window casing recesses and having the top portion of the 7 frame recessed to allow the bottom portion of a window sash to nr0]ect into the recess,

a portion of the ventilator frame extending upwardly overlapping the bottom of the CHARLES L. HARRISON.
